Abstract:Regarding the shortcomings of the cross-coupling control structure during the start-up of a multi-motor with load-namely, a large synchronization error and a long start-up time-this paper proposes a fuzzy self-adjusting cross-coupling control structure. This structure combines a fuzzy self-adjusting filter and an advanced synchronization compensator. The fuzzy self-adjusting filter adjusts the "softened speed", a newly established concept, so that each motor follows the trajectory of the softened speed during start-up, thus effectively reducing the synchronization error of the starting process. The advanced synchronization compensator is added to shorten the adjusting time of the motors. In addition, this paper analyzes the synchronization performance of the structure when the steady state is interrupted by a sudden step of load. Finally, this paper establishes an experimental platform for a synchronous speed control system for a permanent magnet synchronous motor, and verifies the effectiveness of the proposed structure and the correctness of the theoretical analysis through performing experiments.

“…Koren [9] estimated contouring errors as linear relationships with the drives' tracking errors, and compensated the contouring control signals to the velocity loop of each drive with the cross-coupled controller scheme (CCC). Further enhancements of the CCC mainly focused on developing an accurate contouring estimation algorithm [10][11][12][13], or designing new compensation structures [7,14,15] to improve the contouring accuracy. Koren and Lo [10] designed a variable gain CCC as an extension of [9] to improve the estimation accuracy of contouring errors for nonlinear trajectories.…”

“…Later, Huo et al [13] proposed a similar approach as presented in [12] by estimating the contouring errors from the actual and reference positions of the machine. In order to simultaneously improve tracking and contouring performances, Su and Cheng [14] designed a position error compensator combined with the cross-coupled controller. Shih et al [15] and Yang and Li [7] developed new CCC structures for bi-axis contouring paths.…”

“…The biaxial motion system has found numerous applications in mechatronics occasions, including precision machining, spinning, steel rolling and so on [1][2][3]. In a biaxial system, a couple of servosystems are usually linked by a sliding table or other mechanical structure, and control the object to track the position trajectory through synchronous motion.…”

The stability and synchronous performance are usually hard to be improved simultaneously in the biaxial cross-coupling position motion control system. Based on analyzing the characteristics of the cross-coupling control system, a robust adaptive cross-coupling control strategy is proposed. To restrict influences of destabilizing factors and improve both of stability and synchronous performance, the strategy forces dual axes to track the same reference model using Narendra adaptive control theory. And then, a robust parameters adaptive law is proposed. The stability analysis of the proposed strategy is conducted by applying Lyapunov stability theory. Related simulations and experiments indicate that the proposed strategy can improve synchronous performance and stability simultaneously. biaxial motion, motor control system, position tracking, robust adaptive control, cross-coupling, synchronous error Citation: Chen W, Wang D D, Geng Q, et al.
